Product details
Overview
DG453EY-T1-E3 from Vishay Siliconix is a high-voltage quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, 4 Ω typical on-resistance, ±15 V analog signal range, and 44 V supply rating-designed for precision audio/video switching and relay replacement in industrial test equipment.
For engineers reviewing the DG453EY-T1-E3 datasheet, DG453EY-T1-E3 pinout, DG453EY-T1-E3 application, or DG453EY-T1-E3 equivalent, key selection criteria include break-before-make timing (70 ns at +12 V), on-resistance flatness (0.25 Ω typical), charge injection (1 pC at +12 V), and dual-supply compatibility (±5 V to ±15 V or +12 V single supply).
Technical Context
The DG453EY-T1-E3 implements four independent CMOS transmission gates with complementary logic control: IN1/IN2 drive SW1/SW4 (NC), while IN3/IN4 drive SW2/SW3 (NO), enabling simultaneous NC/NO routing in one package. Its architecture supports bidirectional conduction, rail-to-rail analog signal handling, and TTL/CMOS-compatible digital inputs (0.8 V/2.4 V thresholds).
It operates across three supply configurations: ±5 V, ±15 V, or +12 V/0 V, with guaranteed performance over –40 °C to +125 °C. All switches exhibit ultra-low power dissipation (18 µW typical) and fast switching (tON = 132 ns, tOFF = 61 ns at +12 V), supported by internal ESD protection (2 kV HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (dual supply) or 0–12 V (single supply): enables full-rail signal switching without clipping in precision instrumentation. |
| On-Resistance (RON) | 5.5 Ω typical at +12 V: ensures minimal insertion loss and voltage drop in low-distortion audio paths. |
| On-Resistance Flatness | 0.94 Ω typical at +12 V: maintains consistent gain and THD < 0.04 % across signal swing in sample-and-hold circuits. |
| Break-Before-Make Delay | 70 ns at +12 V: prevents momentary shorting between NC/NO paths during state transitions in safety-critical routing. |
| Charge Injection | 1 pC at +12 V: minimizes voltage glitch on sampled nodes, critical for 16-bit+ data acquisition accuracy. |
| Off-Isolation (OIRR) | –60 dB at 1 MHz: suppresses crosstalk between active and inactive channels in multi-signal video/audio systems. |
| ESD Protection | 2 kV HBM: provides robust handling during PCB assembly and field service without external protection diodes. |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012, 7.5 mm × 10.3 mm body, 1.27 mm pitch). RoHS-compliant, Pb-free matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | Active-high logic drives NC (IN1/IN2) or NO (IN3/IN4) switches; 0.8 V/2.4 V thresholds ensure TTL/CMOS compatibility. |
| 5, 6, 13, 14 (S1–S4) | Switch source terminals | NC channels (S1/S4) connect to common when IN1/IN2 = 1; NO channels (S2/S3) connect when IN3/IN4 = 1. |
| 7, 8, 11, 12 (D1–D4) | Switch drain terminals | Signal output nodes; bidirectional conduction allows use as input or output depending on system topology. |
| 9 (V–) | Negative supply rail | Supports dual-supply operation down to –15 V; clamps signals exceeding V– via internal diodes (max 30 mA forward current). |
| 10 (GND) | Ground reference | Logic ground for VL and digital interface; isolated from analog signal path to minimize noise coupling. |
| 15 (V+) | Positive supply rail | Accepts up to +44 V; sets upper analog signal limit and defines RON performance (e.g., 5.5 Ω at +12 V). |
| 16 (VL) | Logic supply input | Separate 5 V rail powers digital interface independently of analog supplies, enabling mixed-voltage system integration. |
Key Features
| Feature | Design Value |
|---|---|
| Two NC + two NO configuration | Enables fail-safe signal routing (e.g., default path active during logic fault) without external logic or redundancy components. |
| Rail-to-rail analog conduction | Signals from V– to V+ pass unclipped, supporting ±15 V op-amp interfaces and industrial sensor conditioning stages. |
| Ultra-low 18 µW power dissipation | Reduces thermal drift in densely packed ATE racks and eliminates heatsinking in portable test gear. |
| Pin compatibility with DG411/DG412/DG413 | Allows drop-in upgrade from legacy Vishay switches without PCB redesign or firmware changes. |
| Guaranteed –40 °C to +125 °C operation | Validated for under-hood automotive diagnostics, avionics I/O modules, and industrial PLC analog backplanes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4532ESE+ | Higher RON (12 Ω typical), no break-before-make spec, +15 V/–15 V only (no +12 V unipolar support) | Suitable for lower-speed industrial I/O where 132 ns tON is acceptable; lacks DG453EY-T1-E3's 1 pC charge injection advantage | Select when cost sensitivity outweighs precision requirements and unipolar supply operation is unnecessary. |
| ADG1434BRUZ | Lower RON (3.8 Ω), higher supply rating (+33 V), but requires external level shifters for 5 V logic control | Better for high-bandwidth video (300 MHz BW) but adds BOM complexity; not pin-compatible with DG453EY-T1-E3 SOIC layout | Choose for RF/microwave test systems needing >100 MHz isolation, accepting added design effort for level translation. |
Compared with MAX4532ESE+ and ADG1434BRUZ, DG453EY-T1-E3 uniquely balances low charge injection (1 pC), unipolar/dual-supply flexibility (+12 V or ±15 V), and native SOIC pinout-making it optimal for space-constrained, mixed-supply precision instrumentation where signal fidelity and layout reuse are critical.

FAQ
What is the maximum allowable analog signal voltage range for DG453EY-T1-E3 when operated with ±15 V supplies?
The DG453EY-T1-E3 supports an analog signal range of ±15 V when powered by ±15 V dual supplies, meaning signals from –15 V to +15 V can pass through the switch without clipping or damage. This is explicitly specified in the "Analog Signal Range" parameter under dual-supply conditions in the datasheet (Document Number 74470, page 2), and applies to all four channels simultaneously.
Does DG453EY-T1-E3 require external pull-up or pull-down resistors on its digital control inputs (IN1–IN4)?
No, DG453EY-T1-E3 does not require external pull-up or pull-down resistors. Its digital inputs have TTL/CMOS-compatible thresholds (0.8 V low, 2.4 V high) and specify input currents of ±0.5 µA max across temperature, allowing direct connection to microcontroller GPIOs or FPGA outputs. The device draws negligible static current (18 µW typical), so no biasing is needed for stable logic states.
Can DG453EY-T1-E3 operate reliably at +125 °C junction temperature?
Yes, DG453EY-T1-E3 is fully specified and guaranteed over –40 °C to +125 °C ambient temperature (per Ordering Information table, page 2), with all key parameters-including RON, leakage, and switching times-tested and binned across this range. Thermal resistance (θJA = 125 °C/W for SOIC) confirms safe operation at +125 °C with ≤400 mW power dissipation, well within its 600 mW absolute max rating.
How does the break-before-make timing of DG453EY-T1-E3 prevent signal shorting during channel switching?
DG453EY-T1-E3 enforces a minimum 70 ns break-before-make delay (tD) between NC and NO channel transitions at +12 V supply, verified in Figure 2 of the datasheet. This ensures the NC path opens fully before the NO path closes, eliminating momentary shorts that could damage downstream circuitry or corrupt measurements in precision analog systems.
Is DG453EY-T1-E3 pin-compatible with the older DG413EY-T1-E3, and what design benefits does that provide?
Yes, DG453EY-T1-E3 is pin-compatible with DG413EY-T1-E3 per the datasheet's Functional Block Diagram and Pin Configuration section (page 1). This allows direct replacement in existing SOIC-16 layouts, delivering immediate improvements in on-resistance (4 Ω vs. 35 Ω typical), charge injection (1 pC vs. 25 pC), and supply range (±15 V vs. ±12 V) without PCB rework or firmware updates.
